In this work, the settlement deformation of soft-soil subgrade and law geogrid were studied based on field tests carried out pile-supported reinforced embankment Rongwu Expressway in Xiong’an New Area. The reinforcement area underlying layer embankment, transverse longitudinal sections subgrade, bidirectional analyzed. results show that reducing pile spacing height can effectively reduce founda...

The strength and deformation properties of maritime geotechnical structures made primarily calcareous sand are critical for project safety. geogrid reinforcement is developed as a promising approach to improve the mechanical sand. This study investigates property biomodified via microbially induced calcite precipitation (MICP) process effectiveness A series unconsolidated undrained triaxial exp...

In this paper, the particle shape factor of stone in soil-rock mixture was used as specific research object geogrid pull-out test, combining random generation method and evaluation criteria rock blocks mixture, a feasible for classifying stones according to their factors is presented. By comparing mechanical behavior composed with different material tests under working conditions, we studied it...

Geosynthetic materials have been demonstrated to be an accurate element in civil engineering, specifically the field of pavement. Regarding implementation these asphalt mixture layers, geosynthetics, such as geotextile and geogrid, used delay crack propagation and/or increase fatigue life. However, use material is based on experience learned or results obtained from testing a reduced scale labo...

The stability of the embankment’s slopes is a critical aspect geotechnical engineering and it essential to guarantee effectiveness factor safety prevent any potential failures in slope both during post-construction. current study consists two parts; first part behavior geogrid-encased granular columns their interaction with soil at shear surface generated by slippage soil, while second changing...

Modular Geogrid Reinforced Soil (GRS) retaining walls, as flexible structures, usually have a certain deformation capacity. However, the damage of facing panels will directly affect durability performance wall and pose threat to safety operation road related facilities. In order study influence different load factors on mode failure characteristics wall, an indoor large-scale model test was car...

Highway widening has become an effective way to improve the carrying capacity of existing expressways. However, assume that differential settlement between new and old subgrades is not controlled. In case, it will lead longitudinal cracks on pavement, which seriously affect safety vehicles. this study, variations elastic modulus dynamic under traffic load were studied by tests. A hyperbolic mod...

Asphalt is a kind of temperature-sensitive material. With the decrease temperature, deformation capacity an asphalt mixture will be significantly reduced. When temperature greatly reduced, layer produce large shrinkage tensile stress and strain, resulting in cracking. Therefore, cracking resistance behavior essential for asphalt. In order to study geosynthetics-reinforced under lower temperatur...
